Episode 18: Practical Test I

Hello, welcome back to Attacking Vitamins. I'm Lee Hyunwook 8p.

This is the 18th episode of the series.

So far we've learned theories and techniques for attacking.

Today, we'll solve problems based on what we've learned.

You can apply what you've learned to some typical situations, and this will help you to improve your attacking skills.

Let's begin today's lesson!

Here's our first problem.

We'll start with some basic problems.

Let's have a look.

This sort of situation often occurs in real games.

White invaded at 3-3 and settled her group in the top left.

As a result, this white group became weaker.

Therefore, black should attack it.

How should black do so here?

If you've paid attention to the lessons so far, you'll soon figure out the answer.

Let me give you some hints.

This knight's move might come to mind first.

So that's one option.

Or, this move is also conceivable.

And this attachment is a more aggressive move.

These three moves are the options.

I suggest that you think about which one is best.

Q. What's the best way to attack?

Hint: ******* moves win running battles!

How should black best attack white's group?

Have you come up with your answer?

Let's see what the best move is here.

Let's try this attachment first.

I'd say this is the most aggressive attacking move.

White will hane, then black should extend.

There's a Go proverb which says, "don't attach when attacking".

Black attached to white's weak group.

If white plays this tiger's mouth, she can make eye shape very easily.

If black tries to capture this group, white can move out.

This group is flexible, so black can't attack white effectively.

If black encloses like this, white can live on the inside.

So don't attach to weak groups.

I think this is the worst way to attack in this case.

But I don't imagine that many of you chose this attachment.

However, it can be hard to choose between these two options.

Let's look at this capping play first.

White will move out like this.

If black plays a knight's move, white pushes and jumps like this.

If black jumps, white makes a bamboo joint.

After that, white can push and cut black later.

In addition, this cutting point is nasty for black.

Black's position is thin.

There are two cutting points, and white escaped too easily.

So this isn't the answer either.

In this case, you need to heed the Go proverb from earlier.

It's time to play a knight's move.

White should attach, or answer here.

Then playing another knight's move is good.

If black keeps playing like this, white won't be able to break out.

If white jumps here, black can defend his moyo.

White can't go any further.

Consequently, white has to live on the inside.

White will live fairly easily.

However, black's developed a large framework on the right.

This was the purpose of black's attack.

Since white left her group vulnerable, black should take advantage of it.

This knight's move is the best way to attack white.

Here's another practical attacking problem.

I imagine you'll face this kind of situation against stronger players.

Let's have a look and learn how black should attack.

I imagine you've encountered this kind of situation several times.

Perhaps you lost some points because you didn't know how to play here?

White jumped here to make shape.

Now black wants to attack white's three stones.

Among the various options, this knight's move comes to mind first.

Even though it looks a bit slow, this kosumi is another option.

And this attachment is the most aggressive move.

These three moves are black's options.

Which move is best for black?

Q. How should black attack white at the top?

Hint: Take away your opponent's ****!

I imagine many people will have figured out the answer by now.

This knight's move is the first option I gave you.

If white attaches here, black can keep attacking the group effectively.

This is a good attack for developing influence.

However, white will attach here instead. Then black has to block.

After that, white extends and bumps like this.

White can easily live on the inside.

Black has to connect, then white hanes here.

This group lived too easily.

Even though black tried to enclose white, she managed her group well.

This isn't the ideal attack for black.

Therefore, the knight's move isn't always good.

I'd say this move is a bit loose in this case.

I imagine many players would have chosen this move.

How about the kosumi?

It may look strange, because it's a slow move.

But if white blocks, then black can attack white's group with this knight's move.

Clearly this white's group is uncomfortable.

White's position is over-concentrated and she can't attach here now.

Therefore, blocking here bad for white.

Instead, white should move out into the center.

Then this knight's move is a good followup.

It's similar to the previous problem.

If white attaches, black extends here.

White has no problem with managing her group, but black will still make it heavy by peeping.

Since white can make two eyes on the inside, this group will be chased for a while.

While attacking, black can strengthen the center and the left side at the same time.

I think this is the ideal attack for black.

Let's look at the last option. This attachment is an overplay.

White will hane and capture this stone.

Even though this atari is pleasant, white lives too easily.

It's a big loss in terms of territory.

So the attachment was a bad choice in this case.

Therefore, taking away white's eye shape is the answer.

Here's another practical problem.

However, this one is harder than the previous problems.

It requires you to do some reading.

The move I'd like to show you is famous, so I prepared this problem for you.

Let's have a look.

Up to here, it's a peaceful opening.

These three stones are the target now.

Black wants to attack this group.

Because of this stone, white's group looks flexible.

But, if you find the vital point, you can attack it severely.

If white plays a kosumi, she can live easily.

So this attachment is one option.

Similarly, this attachment is also conceivable.

It intends to take away white's eye shape.

This move is the last option.

It's hard to explain, but it looks very thick.

It prevents white from playing a tiger's mouth here.

Amongst these three moves, there is but one answer.

Let's try to find the answer now.

Q. Where's the vital point in white's position?

Hint: The opponent's vital point is your own!

You may find this problem hard.

There are many options in this situation.

Let's try the move which comes to mind first.

I think this attachment would be chosen by many players.

White shouldn't hane here. Black will cut immediately.

If white ataris, black comes out.

White can capture these two stones, but the corner will still be captured.

It's a disaster for white.

So white mustn't hane in response to black's attachment.

This bump is the only option.

After this tiger's mouth, black has to answer here.

White will play here, and it seems white's position is flexible.

This group is nearly alive. Black has a weakness here.

It's failure for black. He allowed white to live too easily.

So this attachment isn't the answer.

Let's try this move then.

I'd say this is an advanced technique.

If white captures this stone, black can build influence on the outside.

Black sacrificed his stone, but his moyo became very solid.

This is a success for black.

However, white won't capture this stone.

Instead, this tiger's mouth is a nice move.

Black can't separate white like this.

If white cuts here, black has to capture this stone now.

Then white will capture this black stone. It's no good.

This is a typical example of failure in this situation.

You should remember this move, since you'll face this situation frequently.

I suppose you know the answer by now.

Even though it looks slack, this move is best.

It seems like white can easily live with this kosumi.

But now, this attachment works well.

If black cuts, white can't connect here.

White's group will be separated.

White can't withstand it.

If white captures this stone, black can take the corner like this.

It's quite profitable for black, and this group isn't alive yet.

So it's also painful for white.

Because of this attachment, the kosumi isn't good.

And if white kosumis here, black can attach like this. It's different to the previous variation.

White could bump and play a tiger's mouth before.

But because of this stone, white can't make two eyes now.

So white has to fall back, then black extends here.

White's position is much weaker than in the previous variation.

Black already gained many points, and white has to jump out like this.

After that, black can chase and continue to attack.

Because black occupied the vital point, white's shape collapsed.

Since this is a practical variation, I think it will be very helpful to you in your own games.

We've solved several problems today.

How did you like it? Do you feel more confident about attacking now?

Some of you may have found them easy.

Since this was our first lesson solving problems, I prepared relatively easy ones for you.

We'll continue with harder problems next time.

Be prepared. Thank you!
